Hello,
I would also like to suggest looking at the AD8338 low-power VGA. It has an AGC circuit built in, similar to the AD8367. Unlike some of the other suggestions, the AD8338 is ideally suited to "Baseband" applications from about 300Hz to 18MHz. This VGA is actually a very potent part, with a lot of extra features built in. (Please refer to the app note for more information http://www.analog.com/static/imported-files/application_notes/AN-1192.pdf )
If you could provide us with a general block diagram, I think we can find the best solution possible.
Cheers,
-David
